Pressure self-sealing gate valve gate along with the valve stem for linear movement, usually in the lifting stem has a trapezoidal thread, through the valve top of the nut as well as the valve body on the guide groove, the rotary movement into a linear movement, that is, the operating torque into the operation of the thrust. When the valve is opened, the passage of the fluid is completely clear when the height of the gate lift is equal to 1:1 times the through diameter of the valve, but this position cannot be monitored during operation. In actual use, it is the apex of the valve stem as a mark, i.e., the position of opening motionless, as its fully open position. In order to take into account the locking phenomenon that occurs when the temperature changes, the valve is usually opened to the apex of the position, and then reversed 1/2-1 turn, as the fully open position of the valve. Therefore, the fully open position of the valve, according to the position of the gate to determine.
